Overview

What they do
Founded in 2016 by Fernando Castiñeiras, Athos Capital is an independent venture capital firm focused on early-stage digital and technology startups. In 2021, the firm absorbed Capitana Venture Partners, a move that consolidated its market position, expanded its partner base, and increased its assets under management. Athos Capital is known for its hands-on approach-leveraging its partners' extensive backgrounds in management consulting and M&A-and its flexibility in round dynamics. They have built a strong reputation in the Spanish ecosystem, frequently co-investing with prominent corporate venture arms and international funds.

What they look for
Athos Capital invests in early-stage digital ventures with global ambitions. They are sector-agnostic but have a strong preference for capital-efficient business models that solve real-world problems through technology. The firm looks for high growth potential, a highly scalable business model, and a strong management team. Crucially, they require startups to have a validated product (MVP ready) and demonstrable early adoption or traction.
